On my HP z820 Flashchip is Winbond 250128FVFG, a big chip with 16 pins.
Also, present jumpers (if I remember, memory lock) E14 dual pin, and J20 triple pin.
Several software possible to find to read Flash under DOS or UEFI, but I’m not sure in the fullest RAW dump. And yes - CH341A flash writer works with similar chips (clips with 8 pin). I use it once with HP Elitebook.
@Minzak - What is your BIOS chip ID? Read it with your eyes, don’t rely on software to tell you the ID. I will tell you best software/version to use to dump BIOS, you send to me, then we test the edit Unless you already know what software can properly read and write to this chip?
Hm, for me used hardware flash chip writer - it is easy. But hand-made BIOS can be in the wrong format and MB can brick or revert or just not boot. Need triple recheck, or better automate it! to build an NVME injector in the new version of BIOS. I want to be fully secured and sure in the file before flash it. (I haven’t second Z820 MB ))
@Minzak - Since system has ME jumper, put on jumper, reboot to windows three times, then dump BIOS region with FPT, do NVME edit, then flash it back. If you are not sure, or do not trust your own NVME edit, then send me your dump BIOS region, or programmer dump if you want, and then I will do NVME mod for you
@Minzak - This maybe can be done with FPT, no need for programmer, unless you are worried to try and sort that way? I don’t think @gloobox ever tried to dump and edit just the main DXE volume, instead of entire BIOS region. It should be possible, you can confirm by showing me image of this FPT output (use FPT from V8 ME system tools package) >> FPTw.exe -i Do this with ME/AMT jumper on, after you reboot to windows three times.
@Lost_N_BIOS At last, I got the SOIC16 clip, just need soldering to wire it. But interesting - I haven’t 40 pin, "E1/JP1 SPI BIOS ME/AMT Flash Override Header", only empty pins.
Total Accessable SPI Memory: 16384KB, Total Installed SPI Memory : 16384KB
FPT Operation Passed
And one main question - if I haven't SPI pin, it is mean that I can reflash the BIOS only via SOIC16 clip? Hm, One way is to use a pin to close the contacts.

@Minzak Thanks to try so many jumper work on Z820! Actually I have tried almost all jumpers on Z620/Z420,but it still prompted error7 when flashing with FPT.
But I have some strange, after reboot and dump again BIOS - md5summ is different. I think it always is similar behavior because in ME region rotated some data. And for this reason on forums present messages about clearing ME region when making BIOSes.
Or I wrong, and each next dump must be with the same md5sum ? I put in archive my dumps from flashrom(linux) and ftk8 fpt(dos) and some others - https://bizlevel.net/z820.tar.gz
Some strange, I can’t detect BIOS chip when using 16SOIC Clip, I rechecked wire, but nothing (
I Also have Z220 SFF PC, Planned to make the test on in, before to do on Z820. One bad thing - BIOS on z220 too closely to DIMM, because I cannot use CLIP ((
